Hello,
You are correct that poweroff and halt do not function properly in busybox on
the TS-7500, this is a known issue but does not necessarily present a problem.
In a poweroff or halted state, the CPU still consumes the same amount of
current as everything is still actually active and running, so there is no
benefit to halt or poweroff the system.
The reason this would save power in modern desktop PCs is because the
motherboard has the ability to turn off its power supply, embedded systems
usually do not. If this is what you are looking to do, you would need to
design a power supply that could be controlled by a DIO of the TS-7500 or a
relay on the TS-752 baseboard. A well designed electrical interlock would
waste very little power while the power to the SBC is disabled.
